。 An irradiation tube with an open end that covers the flame is installed in the furnace in front of the burner, while an O 2 -C sensor is used to detect the amount of oxygen and carbon monoxide in the combustion waste gas inside the furnace.
An O detection meter is provided, and an air-fuel ratio controller is provided that can control the amount of fuel and air supplied to the burner so that the excess air ratio is 0.8 to 2.0 based on the detection signal of this O 2 -CO detector. A heating furnace further comprising an air-fuel ratio setting device that determines a range of air-fuel ratios to be controlled in advance based on the amount of fuel supplied to the burner.
